Add MOI wrapper

Updates for MOI 0.8.2 (#84)

* Updates for MOI 0.8.2

* Bump versions of test/MINLPTests

Support for Julia 0.7/1.0

v0.4.2

Compat version lower bound

Bug fix for sol file parsing

Fix bug in sol file parser if the file begins with empty lines. (#81)

* Fix bug in sol file parser if the file begins with empty lines.

* Add tests

* Ipopt solver name changed from ipopt to ipopt.exe in Windows at some point.

v0.4.0

Contains various fixes including better error messages when the solvers fail, and syntax upgrades for Julia v0.6.

Breaking changes:

• No longer conditionally import CoinOptServices and Ipopt. Therefore, BonminNLSolver, CouenneNLSolver, and IpoptNLSolver now throw an error.
